MeasureNet Adds Parr Solution Calorimeter to Lineup

March 22, 2007

MeasureNet Technology is introducing the first of a series of new capabilities for 2007 with the Parr 6755 Solution Calorimeter. As a teaching instrument, it has an important place in college and university laboratories for demonstrating the fundamentals of thermochemistry. The pairing of the calorimeter with a MeasureNet workstation provides a very cost-effective package by eliminating the need for the usual stand-alone thermometric data-logging interface.

Any liquid-liquid or liquid-solid chemical reaction where heat is evolved or absorbed within a temperature range from 10° to 50°C can be studied in the 6755 Calorimeter.

Heats of Reaction, either endothermic or exothermic, can be determined in many different systems, ranging from simple acid-based reactions to more complicated redox, chelation, hydrolysis, hydrolysis and other reactions. The heat of solution produced when a solid dissolves in a liquid can be measured easily. Similarly, the calorimeter can be used to measure the heat of dilution produced by diluting a solution with solvent or with a solution of a lower concentration. It will also measure the heat of mixing, produced when two liquids are combined.

Reactions in the 6755 Calorimeter are conducted in a fully silvered glass Dewar (48 mm inside diameter x 103 mm deep). The stirring mechanism consists of an externally mounted electric motor with a drive belt that turns the stirring shaft at a constant speed (approx. 450 rpm) with no slippage and very little bearing friction.

MeasureNet Technology Ltd. manufactures patented, network-based data acquisition interfaces for science teaching laboratories. It is a spin-off of the University of Cincinnati's Department of Chemistry and is headquartered in Cincinnati, Ohio. Measurenet's award-winning, PC-reducing design helps reduce laboratory maintenance and operational costs while giving students access to high quality shared UV-vis spectroscopy, gas chromatograph connectivity, and an array of innovative probeware. Its acclaimed intuitive design provides improved transparency to enable better science-focused, not technology-focused, learning. Winner of the Ohio Governor's Award For Excellence in Energy Efficiency, MeasureNet networks are found in universities, community colleges, high schools, and vocational training centers across the United States and around the world.
